Based On The Isa Data Acquisition And Processing

In this paper, ISA Bus-based Data Acquisition system and Processing, The implementation of hardware and software is presented in detail. Three kinds of filtering method, averaging, SavitzkyGolay and Kaiser windows LPF, are employed to reduce the noise. To effectively increase the system sampling rate, We use interpolation, and give the comparison of rectangle window interpolation and Kaiser window interpolation. The method of least square is presented to correct DAQ system. Several suggestions are made for further improvement of the new system.
